Human rights advocates say that Canada’s euthanasia laws lack necessary safeguards, devalue the lives of disabled people and are prompting doctors and health workers to suggest the procedure to those who might not otherwise consider it.

Equally troubling, advocates say, are instances in which people have sought to be killed because they weren’t getting adequate government support to live.

Euthanasia “cannot be a default for Canada’s failure to fulfill its human rights obligations,” said Marie-Claude Landry, the head of its Human Rights Commission.

Landry said she shares the “grave concern” voiced last year by three U.N. human rights experts, who wrote that Canada’s euthanasia law appeared to violate the agency’s Universal Declaration of Human Rights. They said the law had a “discriminatory impact” on disabled people and was inconsistent with Canada’s obligations to uphold international human rights standards.
